V3 Migration with Quickstarts and Virtual calendars

Are V2 Quickstart apps able to be migrated? I am migrating one as a test subject but for some reason my virtual calendars are not migrating properly. The migration report has a null grant_id and a migration status of null… and they don’t show up under accounts. Any help? Note: I did verify that my connectors includes virtual calendar support on both applications before trying to migrate accounts.
